European maize meeting report
Thursday, November 1, 2018
In early September John Morgan and Simon Draper attended the European Maize Meeting (EMM), this year held in Belgium, on behalf of the MGA. The meeting, hosted jointly by the Belgian maize organisations, Uclouvain and CIPF, was held in Gembloux, approximately 50 km south east of Brussels and as in the past consisted of three elements.
A classroom-based session when the Status of the Maize Crop in different countries was outlined by our hosts.
This year’s chosen subject was Undersowing and the Impact of Undersowing on Nutrient and Soil retention.
Moving silage
Thursday, November 1, 2018
In his latest Technical Note for MGA members, Mike Wilkinson outlines procedures for moving silage from one place to another prior to use. Mike can be contacted via the MGA office.
Silage is in short supply and may have to be moved from one site to another before use. The material may have been stored in a bunker or temporary unwalled heap (field clamp or pile) some distance from place of use because existing silo capacity was inadequate, or because insufficient silage was made on site to meet demand.
Short maize - What feed value will it have?

Health hazards from silage
Monday, August 20, 2018
Silage making can be a relatively uncontrolled fermentation process. The main fermentation activity in the silo is the conversion of plant sugars to acids. The reduction in pH preserves the ensiled crop from rotting during the storage period provided oxygen is excluded from the silage.
Well-made silage is a safe feed for livestock, but things can go wrong with the fermentation. Hazards to livestock and human health from undesirable micro-organisms in silage are discussed in the article.
Costs of production
Monday, August 20, 2018
The latest in the Costs of Forage Production series is based on average yields and quality. Costs of production are assume contractors undertaking establishment and annual management tasks with crop nutrients being supplied by straight inorganic (bagged) fertiliser. No feed out costs or waste are included.
Westerwolds offer a real opportunity
Monday, August 20, 2018
The hot, dry conditions have hit/ obliterated most second and third cut silages, as well as impacting on many maize crops, to the point that many growers are currently short of grazed grass as well as being down on forage stocks for the winter. The likely early harvest of maize this autumn and recent rain does offer some opportunities to fill the forage gaps, as do extending grazing in the autumn and hopefully next spring.
Drought & Maize
Monday, August 6, 2018
In this special Technical Note for MGA members, Mike Wilkinson outlines prospects for the 2018 maize crop and its likely feed value.
Introduction
This year’s weather to date in large parts of the UK has comprised a wet spring followed by drought. Many MGA members are short of feed and are taking steps to secure additional supplies for the coming winter. A lot of hay and whole crop silage has been made. Some members are suffering from failed maize crops due to prolonged lack of soil moisture.
What are the prospects for the maize crop this year and how might maize silage feed value differ from a normal year?
Topical Issues in Nutrition 2018
Monday, August 6, 2018
Feeding dairy cows during the last six months has continued to provide new challenges for both dairy producers and ruminant nutritionists. This article written by Chris Bartram, head of Nutrition at Mole Valley Farmers highlights several key points to consider. It also pinpoints a few areas that are likely to become more important in the future.

HARVESTING MAIZE – EFFECTS ON QUALITY
Friday, July 21, 2017
In his 6th Technical Note for MGA members, Mike Wilkinson looks at harvesting and silage quality. Mike can be contacted via the MGA office.
When to harvest?
Changes in forage maize quality with advancing crop maturity are mainly the consequence of changes in whole-plant DM concentration. Post-fertilisation, sugars (mainly fructose polymers and glucose) are translocated from leaf via stem to rachis (cob) and finally to grain where they are polymerised into starch as the grain fills and increases in weight. The progressive changes from sugars in solution to starch in suspension (milk) and then to solid starch is indicated by the rise in milk line from the base to the top of the grain as it matures. This process is accompanied by significant loss of water from the plant. There is also loss of water due to leaf senescence and cell rupture due to disease and/or frost damage.
Chris Bartrams' latest maize nutrition update

European maize meeting - Feeding value of maize silage
Tuesday, November 22, 2016
The chosen subject for this year’s European Maize Meeting, held at the Arvalis Research Station, near La Chepelle St Sauveur in North West France in early September, was “The Feed Value of Maize Silage”. As has historically been the case, participating countries address the subject focused on related research being undertaken in their home states and as a consequence, the papers provide a useful reminder of what is going on in Europe.

Nutrition & maize silage - Latest developments
Friday, September 16, 2016
It is widely recognised that this is a very challenging time for the dairy sector. However, better news now appears to be on the horizon in terms of an increase in the milk price and some stability in the feed market. All aspects of most farm businesses have been challenged in recent months and alternative strategies and options evaluated. This has been particularly relevant for all areas related to nutrition. It is important that despite maize silage having been a consistent part of the diet for many producers in the UK for many years that the nutritional benefits of feeding maize silage continue to be challenged. This article written by Dr Chris Bartram, Mole Valley Farmers head Nutritionist initially considers the basic aspects of the nutritive value of maize silage and then outlines a number of exciting developments in maize silage related research that may be applicable in the near future. It will be part of a series of updates intended to keep members of the association up to speed with various new nutritional developments related to feeding maize silage.
Key Maize harvest tips
Friday, September 16, 2016
The warm dry weather means that the maize crops continue to romp through their growth stages and that harvest will soon be upon us. With this in mind I have had a quick scan through past harvest guides to come up with what I hope will be some useful timely reminders.
Assessing milk per tonne of maize silage
Monday, August 1, 2016
We have heard a lot about the need to improve efficiency of feed use. More milk per kg feed or the same milk from less feed are desirable objectives because in both cases the animal is making better use of each unit of feed eaten, and feed is the most significant variable cost of milk and meat production.
In this article Mike Wilkinson discusses how we should decide which maize hybrids are likely to produce most milk.
His article can be found in the Nutrition section of the website.
Report on the MGA trip to France

Maize harvested and feeding well?
Friday, October 30, 2015
Our appreciation of the tremendous value of maize in the diet makes us keen for it to be in the diet as soon as possible. But, after months of watching it grow and despite the delayed season, it is important that we do not compromise the value of the final crop. A good autumn has been very welcome, but those in marginal areas may struggle to hit harvest targets.
